AUTOMATIC OIL-BURNER.

Specicatin of Letters Patent.

Patented Jan. 15,191e.

Application inea necemberae, isis. serial No. 138,970.

To all whom it may concern:

Be it known that I, ALBERT B. DEEM, al citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Automatic Oil-Burner; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

This invention relates to an oil burner for furnaces or boilers used in locomotives, steam ships, forging plants, glass factories and the like, which is adapted to take the place of the ordinary type of oil burner, reference being had to my prior application Serial No. 101,842, liledJ une 5, 1916. This burner is especially constructed so that car bon will notbe formed from the burnt oil on the walls of the furnace, and while it burns at an even and steady heat, it uses only one-half of the oil that the ordinary burner uses. Y

One of the features of the invention is the needle valve which is pneumatically operable for cleaning out the oil outlet. when it becomes'clogged, so that by the operation of a valve in an air line, the clogging Ina-- terial may be removable from the outlet without taking the burner ofi', and at the same time the sediment or dirt may be blown out of the burner by compressed air so that it will be quickly and thoroughly cleaned. The constructio of my burner makes operation so sim` le that it may be cleaned out at short intervals without losingl any apreciable time, whereby the burner will be Eept in better condition,thereby being more efficient and giving better servico. The cleaning needle is incased so as to be protected from outside injuries and is also provided with, a guide so that the operator cannot break or bend it, as was often the case in the old construction.

Another feature of the invention is the means forfurtherbreaking up the oi l spray which consists `of .a set of cross wires secured directly in the path of the oil stream or spra at the `mouth of the burner.

The ull nature ofthe invention will be understood from the accompanying drawings and the following description and claimst 4 In the drawings, Figure 1 is a plan view this down on the burner. Fig. 2 is a slde e vation. Fig. 3 is a central longitudinal cross section showin the device 1n operative position. vFig. 4 is the same as Eig. 3, showing the device in cleaning posiion. In the drawings there is shown a. burner having a casing 10 with a nozzle casing 11 adapted to be tightly screwed on the end thereof. In said casing there is an oil inlet chamber 12 to -which there is connected an oil line 13. Separated from said oil chamber by an upwardly extending partition 14, there is a reservoir 15 which is adapted to catch any foregin substance or matter which may be deposited by the oil assing over it. Said reservoir has a remova le valve outlet or pet cock 16 which may be utilized `in draining and cleansing the burner.-

Extending longitudinally of the casing 1.0 there is an inclosed passageway 17 havin an end ca 18 secured to the end thereo Through t ecenter-of said end cap there is a small passage or opening 19 which serves as an oil outlet, through which the oil is looking e forced under pressure. Extending longitu,

dinally through said passageway there is a valve rod 20 having a piston 21 secured at one end thereof and a needle point 22 on its other end which has a beveled portion adapted to seat in the opening of the valve 19 with a projection adapted to extend through said opening o f the valve. The iston 21 is adapted to reciprocate in' a cy inder 23 which is closed at one end b a cap 24 which is provided with an inwar ly projecting lug 25 against which said ypiston is adapted to be forced by a coiled spring 26; Said spring surrounds the rod 20 and lrests between the piston and inner end wall of the cylinder so as to return the piston `and rod to the position shown lin Fig. 3 after the. Opf l v a port 28 forming a passageway between l the cylinder 23 and the chamber 12.

There is an air chamber 30 which surrounds the oil 4passageway 17 and the cap 18- and has an inlet 31 suitably connected to a pressure pump or com ressed air chamber,

not shown herein. Said inlet is regulated vbltyll'af butter-ilyyalve ordam er 32 pivoted erein and ,secured on a sha t 33 on which butterfly valve to shut on' or regulate thev there is athu-mb piece 34, for operating said air supply. `In the end of the cap ll-there is an opening' 35 through which themixture passes into thel furnace. Thel air chamber 80 isrcuto from the oil chamber 12 byl a v'mllv 86. so 'that there will be no mixture of air or oil until after the oil has been- -forcedi'nto a spray. 10

is la compl air inlet 37 provided withj (.lo'niifilfi'nicatliig with the cylinder-.23 there a `shut-o valve 38. Connecting 'saidair inletv with .the air inlet 3i there i's a pipe line .Bawhich may befnrmedof flexible steel. tubing;

0n the' cap 18 is an 'inwardly ext tendingY idem .which engages ,the rod 20 so theoil spray.- i y .l

. 4'When the burner is in thepositio'n 'shown as tp h d it in position at all times and guide itintq the opening 19.' On. the otherend of Vsaidcap there v,are outwardly extending lugs' 41 provided withcrossxwires 42 which cross each other directly in .front of the o'per'iingv 19 and further act to break up in Fig. 3, the compressed air enters the chamber surrounding the o'il passage 17 and passes on through theoutlet 35. The

. oil enters through the line 13 under `pres-- sure, vthe oil chamber Aand 'through the o enii'ig 19 vwhere ,it 'engages-thc compresse "air to form an oil Vspra or vapor. The dirt and sediment will be lowii out of the-cham berj12 into the reservoir 15 where it will settle at the bottom or .will be. forced into Vthe opening 19 which occurs .in burners of the ordinary type, thereby clogging-.up'the nozzle and reventing the operaton'of the burner. Wlhen this occurs, the butter-fly valve is closed', as' in Fig. 4, and the valve 38 opened so .that the compressed'` air is 'forced intv the cylinder 2`3 and acts against the piston 1 to'forcethe point `22througl`i the opening 19 for clearing itof any matter that may becloggingit'. The air then esca' es through the passage 28 and being 4shut 'clip from the air chamber 30, has lits only escape through the outlet 16 blowing the sediment and dirt 'out with it. i

" It maybe, therefore, readily seen'that the biirner will be thoroughly cleaned'by closing the butter-ily valve. 32 and 0 eni'ng the valve 38 without dan er of Ibrea ing the needle point 22 or ben ing the rod 20,'A as has heretofore been found' to-be the'- case.-
